The term gingival hyperplasia refers to excess gingival tissue growth. It can be caused by numerous factors, most common being periodontal disease, poor oral hygiene, medications, smoking, and ill-fitting denture prostheses.1,2 The treatment of hyperplasia includes elimination of the causing factors and surgical removal of the lesion.1 If the cause persists, the tissue becomes more fibrous over...

The mainstay of treatment of children with recurrent respiratory papillomatosis has been CO2 laser laryngoscopy. Powered microdebriders allow precise removal of laryngeal lesions without thermal damage. The microdebrider may reduce costs by reducing operative time and limiting the need for expensive laser-related equipment. To compare the use of the microdebrider with that of the CO2 laser in c...

BACKGROUND Genital warts are the most common viral sexually transmitted disease affecting 1% of the population. A prospective, open-label controlled trial was performed to compare topical 5% potassium hydroxide (KOH) solution with CO2 laser in the treatment of female genital warts. METHODS Seventy patients were enrolled in the study after convenience sampling. Right-sided lesions of the patie...

Recurrent respiratory papillomatosis (RRP) is a rare disease, characterized by recurrent proliferation of benign squamous cell papillomas in the larynx as well as in the other parts of the aerodigestive tract. We have compared different treatment options for RRP of the aerodigestive tract including surgical, conservative and combined approaches. A total of 43 patients with papillomatosis that r...

PURPOSE We examined corneal surface response to an isolated thermal load. METHODS Cadaveric porcine eyes were pressurized and stabilized for processing and imaging. A carbon dioxide (CO2) laser (1.75 W) delivered a uniform disk of continuous wave thermal radiant energy to the exposed corneal stromal surface without ablation. Thermal load was determined by measuring corneal surface temperature...

H2 seems the ideal candidate to study ultrashort intense laser-molecule interactions since its simple one-electron structure allows it to be treated accurately by theory. This is aided by the fact that at low intensity (<5×1013 W/cm2) it may be approximated as a two electronic state system. However, as recently pointed out by Posthumus et al. [1], vibrational excitation of H2 , with the populat...

In this paper the process of laser forming has been investigated using an analytical and an experimental method for three levels scans velocity. A coupled analysis has been performed in ANSYS®. Also in order to prove the predictive methods, experiments on thin sheet metals have been done when a laser of a fair power was used. Before done, experiments were designed with full factorial chosen as ...

OBJECTIVES The aim of this study was to compare the effectiveness of the Er,Cr:YSGG (Waterlase) laser with KTP and CO2 lasers in laser assisted uvulopalatoplasty (LAUP) for treatment of snoring. STUDY DESIGN This is a prospective study of 63 patients who were treated for snoring by LAUP either with Er,Cr:YSGG (n = 21) or with KTP (n = 21) or CO2 lasers (n = 21). Histologic analysis was perfor...

context: rapid stretching of the skin over the weak connective tissue leads to development of striae distensae. recently, researchers have shown special interest towards use of fractional photothermolysis in treatment of striae and several studies have shown its usefulness. our aim was to assess the efficacy of fractional co2 laser in treatment of striae alba. subjects and methods: a randomized...

A model is developed for the breakdown and regeneration of component gases in an industrialised TEA CO2 laser, both with and without internal catalysts, and is found to be in excellent agreement with experimental data. The laser was found to be stable at 02 levels in excess of 2%, whereas previously reported values suggest stable operation at values of less than 1%. This is thought to be relate...
